My father is 89 and continues to drive despite the fact that he has had several accidents. He thinks he's a good driver, denies any fault, and refuses to give up his keys. In the most recent incident he hit a person on a bike and claims he never did although the police report says otherwise. My brother wants to give him an ultimatum which puts my Dad in a position of losing dignity. This doesn't seem to be the way to go. Are there programs out there that can evaluate his driving abilities? Any suggestions?
